Application mobile de paiement

Hello, I would like to develop an application for my school that will allow students to pay their restaurant and transportation expenses directly with their phones or student cards. The idea is to have an application. On the student side: they need to be able to top up their accounts either via mobile money or by buying top-ups. They need to be able to see the balance, generate a QR code to pay with the app, or pay with the student card and be debited directly. They need to be able to view top-up and payment history; earn loyalty points or a cash-back system; On the administrator's side: the application must be installed on a payment terminal; they must select either the restaurant option or the transport option; they must receive payments; make a daily and per-meal report of payments received. I'm posting a photo of an equivalent model I've seen that interests me. Are you interested in such a project? How quickly is it possible? How much can it cost? I'd like to install two refill systems. I already have an agreement with a cell phone company.
